FUEL-OIL HEATER.

Appncation filed May 5,l 1923. seriai No. 637,636.

To all whom z't may concern:

Be it known that I, EARLE I. STAPLES, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Fuel-Oil Heaters, of which the following is a specification.

This invention relates to fuell oil heaters and has for its primary object the provision of means for creating an oil film and for lacing same in circulation while sub'ectin the oil to the action of a heating agent and for correlating the agent and the oil, to heat the latter in a highly effective manner.

A further object of the invention is to provide means for subjecting the oil to the maximum action of a heating agent and to quickly heat the oil while causing a circulation of the oil in a structure which automatically acts to relieve the oil of dirt, sano. and water that precipitates from heating the oil.

Another object of the invention is to provide a heater of the character which may be subjected to a cleaning process without the necessity of throwing the heater out of operation at such time. y

With these and other objects-in view, the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are i hereinafter fully described, and particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, in which Figure 1 is a longitudinal section through the heater showing same associated with anv ,oil pump, thelatter being 1n elevation.

Figure 2 is a transverse section through the heater showing the pump in elevation.

Figure 3 is a diagrammatic sectional view of the drum showing a slightly modiiedform thereof.

In carrying the invention into practice, I-

employ a cylindrical drum 10 provided with upper brackets 11, 11Kand lower brackets 12,

12, the latter adapted to constitute supportingfeet for the drumvwhereby it may be firmly anchored to a fiooror other suitable support. The brackets 11 are connected with.

a metallic tray'13v on whicha pump mechanism 14 is supported and vadapted to force steam into the heater in a manner to be hereinafter described.

The drum is provided with concentric cylinders 15, 16, 17 and 18, theends 19 of which are preferably welded to the interior of the head 20 of the drum. .The cylinder 15 has its end adjacent to the head 21 of the drum curved inwardly lat 22 and welded at 23 to the adjacent end of the cylinder 16. The cylinders 15, 16, 17 and 18 are preferably equi-distantly spaced apart and as ilustrated the cylinders 17 and 18 are somewhat longer than the aforesaid cylinders 15 and 16. The said cylinder 17 has its end 24 adjacent tothe head 21 of the drum curved inwardly andl welded at 25 tothe cylinder 18. The said head 21 of the drum 10 1s spaced from the adjacent ends ofthe aforesaid cylinders 15, 16, 17and 18. 'By ar- .Y

ranging Vthese cylinders in pairs it will be observed that concentric chambers 26 and 27 are formed thereby and that these chambers circulatingfs'pace 32 between the cylinders.

16 `and 17.

Leading from the pump mechanism 14 is an oil delivery nozzle 33 which is associated withv a valve 34 so that oil in regulated .proportions can' be discharged to the drum'. This nozzle4 preferably extends through the head 21 land toward the opposite head20 and is interposed in the circulatingspace 35 between the walls of the drum and the adjacent cylinder 15. The

suitable distance from the headV 20 so that 'as oil emerges from the nozzle it is brought into impingement with said head 20 and f16 and' 17 ,the oil finally flows into'the discharge duct 28. Extending into this discharge duct 28A from the head 21 `is a discharge pipe 36 connected exteriorly of the drum with a strainer'37. This 'strainer-is providedwith a pipe `conne,ction 38 adapted discharge end of the' nozzle is vs'pacedfor a to bev-operatively associated in the usual. well-known manner with a burner, not

shown.

Leading from the pump mechanism 14 is a steam pipe 39 having nozzles 4e() andv L11- respeotively ot varying lengths. rilhese nozzles pass through therhead 2.0and'v into,

the respective chambers 26 and 27 so that heatfngJchambersi.

The drun'nis provided. with; a .valved drain' connection; 4a adapted., toi permit ofv` theY drawing. oth sediment from; theA drum while` tlieheater is in.operation-. This fdrai'nivalve: also permits water; of condensation to be discharged from the drum Y as desired.

Due to the relative arrangement-iofV parts' aforesaid iti iollowstliat the heateracts as a4 tilter'ortrap and? that the; saine. autoinatically catches` sand on other.- sediment and water which being` heavier;1 thans oil, precipitates to the bottom: ofi* thex drum where-y ita is; held. against passing through the dischargei pipe'v 36. It? willazbe underfstood'-y that ,when the .delivery pipe; 33? is con= nected;I with the f. pump', pressure will be created in this pipe to induce circulationqol"l oil inr the f heater and an' ellectiveA discharge.i of the heatedy oil inir operative; timel writhia-zthorf ough heatin'groi'v''the' oil-.

InI operationz. oilf flows in' one;` direction into the drumf and'.v it' is iiirst; caused to enterk the"A space V35; It' isa. converted;V into;- a film and is forced in a like manner over'theasunfaces otjthexrespective cylinders .15',` 16,17 and'l18 and? the ballle'w-allfBO, taking aisinuf ousV course'. and finally enteringv the discharge duct: 28.y The; .steam is; forcedinto the chambers 26`and 27 tromithe` opposite end ofthel druin-aaid? the steam initially flows; in arr` oppositezdiiection te. thatsof the oil' as it. comes# from the piper 33.
